Weights AI

Weights AI turns any song into an AI cover, sung in the voice you pick. Choose from more than 2,000 community voice models, from singers and rappers to cartoon characters, video game heroes, anime characters and streamers, or train a private model of your own voice from 10 minutes of singing. Making a cover takes three steps. Pick a voice. Upload a song as an MP3, WAV, M4A, AAC, FLAC or OGG file up to 50 MB, or record yourself singing right in the browser. Then press the button. Weights AI separates the vocal from the music, re-sings it in the new voice, and mixes it back with the original instrumental, so the melody, timing and lyrics stay exactly where they were. Your AI cover is ready in about a minute, and you can download it as an MP3 or play it again later from your history. Pitch matching handles the hardest part of cross-voice covers. If you're putting a male voice on a female singer's song, or the other way round, one setting moves the key so the result sounds natural instead of strained. There's nothing to install and no GPU to rent. Sign in with Google or email and you get free credits, enough to make your first cover. After that, plans start at $6.99 a month, or you can buy a credit pack that never expires. If a job ever fails, its credits come back automatically. Weights AI also includes AI Song Remix, which turns a track into piano, phonk, EDM, lo-fi or a style you describe.
